Little boy thinks he's drowning, he's really not

And that's what big sisters are for.

This poor kid.

He really thought he had gotten himself into a lot of trouble while swimming - he's clinging on to that rope for dear life.

His distress is genuine - until his sister comes along and stands him up. Then he realises he may have overreacted.

Bit embarrassing but at least his only injury is to his pride.
